title: [A clinical study of osteotome sinus floor elevation and simultaneous implant placement in the periodontally compromised patients].
abstract: OBJECTIVE
  To study the clinical effect of osteotome sinus floor elevation (OSFE) combined with simultaneous implant placement in the treatment of edentulous posterior maxilla subject to insufficient bone height in the periodontally compromised patients.
  
  
  METHODS
  Forty-seven Straumanns implants were placed in the posterior maxilla in 35 patients with the procedure of OSFE. The final prostheses were restored after 3 to 6 months. The follow-up period was 6 to 30 months. Radiographs were taken and PD, PLI, BOP were measured and analyzed.
  
  
  RESULTS
  The overall survival rate was 95.74% during the study period. Forty-five out of the 47 implants were clinically stable and loaded without pain or any subjective sensation. The perforation ratio of the membrane was 4.26%. The average of PD around the implants was (3.22±1.07) mm. The average of the marginal bone loss was (1.38±0.59) mm.
  
  
  CONCLUSIONS
  OSFE without bone graft proves to be an effective and predictable treatment for atrophic edentulous posterior maxillary region in patients with periodontitis, but the long-term effect needs further observation.
